Definitions
- the present invention relates to wireless communications and more particularly to a User Equipment (UE) and method for handling Public Land Mobile Network (PLMN) selection involving Proximity Based Services (ProSe) communication.
- UE User Equipment
- PLMN Public Land Mobile Network
- ProSe Proximity Based Services
- Proximity-based applications and services principle is to discover instances of the applications running in devices that are in proximity to each other, and ultimately also exchange application-related data for general and also public safety reasons.
- a ProSe direct discovery and Evolved Packet Core (EPC)-level ProSe discovery is applicable for Public Safety UE and non-Public Safety UE where the ProSe direct communication is applicable for Public Safety UE only.
- EPC Evolved Packet Core
- a UE 100 must perform the PLMN selection for the ProSe communication as specified in 3GPP TS 24.334 and TS23.122.
- the 3GPP TS 23.122 facilitates storing of current Registered PLMN (RPLMN) and current PLMN selection mode during manually triggered actions like “manual Closed Subscriber Group (CSG) selection on a different PLMN” and “ProSe direct communication”.
- the current release of specification 23.122 doesn't consider cases like manual CSG selection over an existing ProSe direct communication or vice-versa.
- the UE 100 might end up overriding the stored PLMN selection mode and the RPLMN leading the UE 100 to an indefinite Limited Service or No-Service during roll back to stored values.
- FIG. 1 is an example of one such scenario, the following are the signaling messages performed between a controller unit 102 of the UE 100 and Non Access Stratum (NAS) layer 102 of the UE 100 :
- NAS Non Access Stratum
- the UE 100 Currently registered ( 110 ) on PLMN1 in Automatic mode.
- the user performs ( 130 ) the manual CSG cell search and selects the CSG cell which belongs to PLMN2.
- the controller unit 102 shall store ( 140 ) PLMN1 and Automatic mode for future roll back and enters manual PLMN selection/CSG cell selection mode for PLMN selection of PLMN2.
- the user now initiates the ProSe direct communication ( 150 ) over the existing manual CSG selection.
- the controller unit 102 has to trigger a PLMN selection again. So, the UE 100 will again save ( 160 ) the current RPLMN and PLMN selection mode i.e. PLMN2 and manual PLMN selection mode.
- the UE 100 will roll back ( 114 ) to the stored values which are update in signal message ( 180 ), i.e. manual PLMN selection mode and the PLMN2.
- the PLMN2 As the PLMN2 was selected due to the manual CSG selection, it may not provide all services to the UE 100 and since the UE 100 is now operating in manual PLMN selection mode, the UE 100 will remain in Limited service or No-Service indefinitely until the user changes the manual CSG cell selection mode or performs another manual PLMN selection.
- FIG. 2 is an example of one such scenario, the following are the signaling messages performed between the controller unit 102 of the UE 100 and the NAS layer 104 of the UE 100 :
- the UE 100 is initially registered ( 210 ) on PLMN1 in manual mode, Network indicated PLMN2 as its Equivalent PLMN (EPLMN) for services in different RAT (example. Network operator-1 in 2G+Network operator-2 in 3G for Network operator-1 subscribers).
- ELMN Equivalent PLMN
- the user performs a manual CSG cell search ( 220 ) and selects a CSG cell which belongs to PLMN3.
- the controller unit 102 shall store ( 230 ) PLMN1 and manual mode for future roll back and enters manual PLMN selection mode for PLMN selection of PLMN3.
- the UE 100 registers on the PLMN3 (CSG) cell.
- the UE 100 When the UE 100 moves out of the coverage ( 240 ) of CSG (PLMN3), the UE 100 will roll back ( 250 ) to the stored values which were saved in at ( 230 ) but the EPLMN list information might have been changed or deleted due to signaling message ( 240 ).
- the UE 100 may end up in Limited service or No-Service ( 260 ) if PLMN1 rejects the UE 100 with a temporary cause or registration is not possible due to poor radio conditions. In this case although PLMN-2 is valid for PLMN selection, the UE 100 will not camp on to that PLMN-2 because the EPLMN list is deleted.
